New isomers in neutron-deficient isotopes of124Cs and127Ba

Abstract

ABSTRACT. By on-line mass separation and subsequent gamma and electron decay-spectroscopy at very low energy, two new isomers,124mcs(TI/2=6.3 • seconds) and 127mBa (TI/2=1.9• seconds) have been identified.

New isomers and their decay in odd-odd neutron-deficient cesium isotopes

“…In our first investigation, in addition to the 31 s activity, five new low-energy transitions have been rapidly identified and assigned to an isomeric state in 124Cs. A (6.3-t-0.3) s half-life had been deduced and already reported [26]. As several experiments have been undertaken to establish energy measurements and multipolarities of the transitions, the half-life estimation has been refined.…”

Effect of Magnetic Field Direction on Texture Evolution in Cold-Rolled IF Steel Sheet at the Initial Stage of Recrystallization

“…The texture was determined from the normal direction (ND) in the 1/4 layer of the specimen using the X' pert MRD type X-ray diffractometer with Co K α radiation. Three incomplete pole figures {111}, {200} and {220} were measured, and they were used to calculate the orientation distribution function (ODF) with the two-step method [11] and the results are presented in terms of constant ϕ=45° section (Roe's notation). The microstructures of the longitudinal sections of the specimens were examined with an optical microscope.…”

Properties of a two-second isomer in127Ba measured with a new technique of laser spectroscopy

“…With this picture one might expect isomeric states based either mainly on the ;+[404] or the $-[523] orbits. A two-second isomer has been observed in IZ7Ba from &decay measurements [3] but this was not subsequently seen in later laser work [l], possibly because of the short lifetime of the state. With this in mind we made a systematic search for long lived states in "' Ba using a newly developed ultrasensitive technique of laser spectroscopy.…”
