251MD cA E,IA$From 2006Ch52, unless otherwise noted.  Intensities have been
251MD2cA renormalized to sum to 100.
251MD c  2006Ch52: {+255}Lr isotope produced by {+209}Bi({+48}Ca,2n) reaction
251MD2c  at 217 MeV, in two separate experiments conducted at JYFL and GANIL.
251MD3c  Recoil products separated from the primary beam in each. JYFL:
251MD4c  Measured recoil products, E|a, I|a, and tof using a Multi-Wire
251MD5c  Proportional Counter gas detector, two Double-Sided Si Strip
251MD6c  Detectors (DSSSD) and a "box" of 28 pin-diodes surrounding the two
251MD7c  DSSSDs. GANIL: Measured recoil products, E|g, I|g, E|a, I|a, ce, and
251MD8c  tof using a "galotte" detector (mylar foil and micro-channel plate
251MD9c  detector), a DSSSD, four cooled Si detectors (BEST) and four
251MDac  segmented Ge detectors (EXOGAM).
251MD c  2008An16: {+255}Lr produced by {+209}Bi({+48}Ca,2n) at 214-244 MeV.
251MD2c  Recoil products separated from the primary beam using the velocity
251MD3c  filter SHIP. Measured recoil products, E|a, I|a, using a
251MD4c  position-sensitive 16-strip silicon PIPS detector. Measured
251MD5c  time-of-flight (tof) using electron foil detectors. Measured E|g, I|g
251MD6c  in prompt and coincidence with alpha particles. Detectors: clover Ge
251MD7c  detector. No gamma-rays were observed (I|g/I|a <0.03).
251MD c  2008Ha31: {+255}Lr isotope produced by {+209}Bi({+48}Ca,2n) reaction,
251MD2c  at 219 MeV, using the U400 cyclotron, Dubna. Activity was separated
251MD3c  using the VASSILISSA fragment separator. Measured |a
251MD4c  particle-energies and intensities, conversion electrons, and |g rays
251MD5c  with Si and Ge detectors.

251MD cA HF$The nuclear radius parameter r{-0}({+251}Md)=1.467 {I15} is
251MD2cA deduced from interpolation (or unweighted average) of radius
251MD3cA parameters of the adjacent even-even nuclides (2020Si16).
