Experimental Study of 4n by Directly Detecting the Decay Neutrons

The tetraneutron has attracted the attention of nuclear physicists during the past decades, but there is still no unambiguous confirmation of its existence or non-existence. A new experiment based on He-8(p, 2p)H-7{t+(4)n} reaction, with direct detection of the four neutrons, has been carried out at RIBF, which can hopefully help to draw a definite conclusion on the tetraneutron system.

Automated summary

The tetraneutron has been a topic of interest for nuclear physicists for decades, but its existence or non-existence has not been definitively confirmed. A new experiment at RIBF, which detects four neutrons directly, may provide a conclusive answer to the tetraneutron system.
