In-beam gamma spectroscopy of As nucleus

The high spin level structure of As nucleus is studied by populating the nucleus in Ni(C,p2n)As reaction. Level scheme is revised significantly. Positive parity sequence is extended up to 33/2 and a negative parity side band is identified and extended up to high spins 37/2. In addition about 15 new energy levels and a total of about 25 new gamma transitions were placed in the level scheme.
