249BK c 2005Ah03: {+253}Es was produced by milking {+253}Cf that was produced
249BK2c in the High Flux Isotope Reactor at the Oak Ridge National Laboratory
249BK3c at three different irradiations done in 1998, 2000 and 2003. The
249BK4c sample produced in the 2003 irradiation was chemically and
249BK5c isotopically pure and provided the most sensitive measurements.
249BK6c E|g, %I|g, |a|g coin for all the three samples were measured.
249BK7c Single low energy gammas (<600 keV) were measured using two different
249BK9c LEPS detectors while a 25% Ge detector was used to measure the high
249BKac energy gammas. |a|g coincidence measurements were peformed with a Si
249BKbc detector for the aphas and a 110% Ge detector for the gammas.
249BKcc Measurements were performed separately with the 2003 sample at Argonne
249BKdc National Laboratory using the Gammasphere array of 99
249BKec Compton-suppressed Ge detectors. |g|g coincidence measurements were
249BKfc measured at Lawrence Livermore National Laboratory using two Ge(Li)
249BKgc detectors. Absolute |g-ray intensities were determined by measuring
249BKhc the alphas from the decay of {+253}Es with a Si detector of known
249BKic solid angle and gammas with a Ge spectrometer whose efficiency was
249BKjc determined with a calibrated source
249BK c 1975Ah01: {+253}Es was produced in the |b- decay of {+253}Cf at Oak
249BK2c Ridge National Laboratory and was chemically purified. |a particles
249BK3c were measured with an array of 14 surface barrier detectors at the
249BK4c Argonne double focusing magnetic spectrometer. Measured E|a and I|a.
249BK5c Deduced levels and hindrance factors
249BK c 1972Bb24 (also 1971Ba49): Alpha decay was studied using the technique
249BK2c of deviation of charged particles in a magnetic field using the
249BK3c magnetic |a-spectrograph. Measured |a spectrum, E|a, I|a
249BK c 1971HoZQ: {+253}Es was obtained from the milking of {+253}Cf at the
249BK2c Oak Ridge National Laboratory. The gamma spectrum from the decay was
249BK3c measured with a Ge(Li) detector. Measured E|g, I|g and K-conversion
249BK4c coefficients
249BK c 1965Ho15: The internal-conversion electron spectrum was measured with
249BK2c the Berkeley 50-cm iron-free spectrometer. Half-lives were
249BK3c determined from indirect measurements of the distance the recoil
249BK4c travelled before emitting conversion electrons using the electrostatic
249BK5c pre-accelerator system in with the iron-free spectrometer.
249BK c 1964Ho10: {+253}Es was produced by heavy-isotope production from
249BK2c neutron irradiations on appropriare target materials such as {+244}Cm.
249BK3c The internal conversion electron spectrum was examined with the
249BK4c iron-free spectrometer. Measured E|g, I|g and conversion electron
249BK5c subshell ratios
249BK c 1963Le17: Alpha decay of {+253}Es was studied using the NaI
249BK2c scintillator for the gammas. In addition, an anthracene scintillator
249BK3c electron detector and an alpha detector consisting of a
249BK4c phosphorus-diffused p-n silicon detector were used in the
249BK5c alpha-electron coincidences measurements
249BK c 1960As06, 1960As08: Alpha and electron spectra of {+253}Es were
249BK2c investigated with high-resolution magnetic spectrographs.
249BK3c Measured |a|g coin., |a-e

249BK c 1990Po14: Measured relative L and M x-ray intensities from the decay
249BK2c using the x-ray spectrometer
