Abstract The goal of this proposal is to perform a thorough investigation, with the instruments onboard INTEGRAL, of the broad band hard X-ray properties of the Bursting Pulsar GRO J1744-28 in case it will undergo an outburst during AO11. We ask to visit the source three times, separated one another by about one month, for a totaloverall time of 280 ks. In particular, we intend to search for cyclotron absorption lines in the X-ray spectrum ofthis object in order to get a direct measurement of the accreting neutron star magnetic field intensity. We alsopropose to: (i) monitor the spectral and timing behaviours of the hard emission from the outburst onset to the decay toward quiescence; (ii) to obtain phase-resolved spectra of the pulsating X-ray emission; and (iii) to pinpoint the differences between the bursting and the persistent fluxes of this source. Other r^ant issues which can be explored with INTEGRAL observations, such as the determination of a pulse period derivative Pdot and the comparison with the other peculiar source MXB 1730-335 (the Rapid Burster) are discussed.This is the resubmission of the proposal on GRO J1744-28 approved since INTEGRAL-AO1

Mission Description The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
