General Comments:

1985La03: First identification of 30Ne in Ta(40Ar,x) reaction at E=44 MeV/nucleon; measured fragment spectra vs mass.

1991Or01: Ta(48Ca,X) at 55 MeV/nucleon. Measured projectile like fragment spectra, mass excess.

1998NoZZ, 1998NoZW: Ta(40Ar,X) E=95 MeV/nucleon at RIKEN facility, measured isotopic half-life.

1999Re16, 1997Ta22 (also 2001Pe14,1999Dl01): 30Ne was produced by fragmentation of 36S beam at 2.8 GeV, time-of-flight and E-ΔE method for identification of fragments, four Ge detectors for γ-ray measurements; GANIL-Dubna collaboration; Measured isotopic half-life and delayed neutron branching. 1997TaZM, 1998AlZV, 1999ReZU, 1999PeZW: previous reports about formation of 30Ne from fragmentation of 36S beam and subsequent half-life measurements.

2017Li07 - 12C(30Ne, 29Ne’), E=228 MeV/nucleon; measured reaction products, deduced σ and spectroscopic factors. Authors suggest for further improvement in the Sm and AMD calculations for the structures of 30Ne and 29Ne, based on the comparison of the measured 1-neutron removal inclusive cross section with the calculated values.

Atomic excess mass measurement: 2007Ju03, 2000Sa21, 2001Sa72.

In 2006Kh08, 38.88 and 33.89 MeV/α beams of 30Ne impinged on a Si target, measured σ=2587 mb 219 and σ=2849 mb 399, respectively, for the Si(30Ne,x) reaction and a reduced strong absorption radius of <r02>=1.347 fm2 97 is deduced and used to study the isospin dependence.
