Abstract

High-spin states in

^{70} As

were populated using the

^{58} Ni

(

^{16} O,

3 p n

) reaction at 70 MeV energy. Lifetime measurements of the

11^{(+)} \to 9^{(+)}

980.7 keV and

{(13}^{+}) \to 11^{(+)} 1342.7 keV

transitions using the Doppler-shift attenuation method determined that both are enhanced

E 2

transitions. This measurement indicates the onset of deformation with increasing spin in

^{70} As,

as has been seen in neighboring nuclei.
