Nuclear Data Sheets for A=235

Spectroscopic data and level schemes from radioactive decay and nuclear reaction studies are presented here for all nuclei with mass number A=235. The highlight of this evaluation consists of the precise and comprehensive Coulomb excitation study (2012Wa35) on U-235, which in addition to the 712[743] ground state rotational band, extended the 1/2[631], 5/216221, 5/2[752], and 3/2[631] rotational bands up to J pi=53/2+, 49/2+, 41/2-, and 43/2+, respectively. This evaluation presents a study (2010Hu02) of the Np-237(Sn-116,Sn-118 gamma) reaction where the ground state rotational band 5/2[642] was observed up to J pi(53/2+). It is worth for historical knowledge to mention the report on the Discovery of isotopes of the transuranium elements with 93<= Z <=98 (2013Fr02), where the information for elements Np, Pu, and Am with mass number A= 235 is given. Cf-235 has not been observed. The alpha hindrance factors (HP) presented in this evaluation were calculated using values of the radius parameter (r(0)) interpolated from those for even-even adjacent nuclei given by 1998Ak04.
