A recoil ion momentum spectrometer has been fabricated for studying angular anisotropies in ion-induced molecular dissociation. The spectrometer is characterized for its time and momentum resolution by studying test cases of ion-atom and ion-molecule collisions. The typical time resolution is measured to be 2.9 × 10-3(Δt/t) and typical momentum resolution is of the order of 32 atomic units. Some preliminary results on the measurements of angular anisotropies in ion molecule collisions are presented. © 2014 Elsevier B.V. All rights reserved.

University of Calcutta (informally known as Calcutta University or CU) is a collegiate public state university located in Kolkata, West Bengal, India.&nbsp;Within India it is recognized as a &quot;Five-Star University&quot; and accredited &quot;A&quot; Grade by National Assessment and Accreditation Council.

&nbsp;

The University of Calcutta has secured the Fifth position among the Universities of India in the prestigious &quot;Indian University Ranking 2019&quot; list, released by the NIRF of the Ministry of Human Resource Development, Government of India.

&nbsp;

It was established on 24 January 1857, and was one of the first institutions in Asia to be established as a multidisciplinary and Western-style university. Its alumni and faculty include several heads of state, heads of government, social reformers, prominent artists, only academy award winner and Dirac medal winner in India, many Fellows of the Royal Society and five Nobel laureates as of 2019 which is highest in South Asia.

We report the formation of H3+ by proton coagulation in methanol under the impact of low energy Ar8+ projectiles. Our time-of-flight coincidence measurements with CH3OD establish that the H3+ formation arises from intramolecular bond rearrangement of the methyl group. We have performed ab initio quantum chemical calculations that show the preferred pathway for C-H3 bond cleavage. Fragmentation of organic molecules like methanol under impact of highly charged ions is suggested as an alternative mechanism of H3+ formation in outer space. © 2006 The American Physical Society.
